{"product_id":"microscopio-biologico-magus-bio-250tl","title":"Biological microscope MAGUS Bio 250TL","description":"\u003cp\u003eThe MAGUS Bio 250TL microscope is suitable for studying thin sections and smears of biological samples. Observations are made using the brightfield microscopy technique in transmitted light. The light source is a 3W LED, and the optical system consists of infinity-corrected plan achromatic objectives. The microscope supports additional accessories, such as darkfield, polarization, and phase contrast devices. This microscope is an ideal choice for analytical work in the lab, research work, and educational purposes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOptics\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe trinocular head includes two eyepiece tubes for observations and a vertical tube for installing a digital camera (not included). The tubes are inclined at 30° for comfortable work during long hours and can be rotated 360° to accommodate the observer's height. There is a diopter adjustment ring on the left tube.\u003c\/p\u003e\u003cp\u003eThe objectives are mounted in a 5-position revolving nosepiece: the kit includes four objectives, leaving one free position for an additional objective. An optional objective can be installed in the free position, which allows increasing the magnification power within the magnification range. During observations, the user can see the objective inserted in the optical path because the revolving nosepiece is oriented inwards. This frees up space above the stage.\u003c\/p\u003e\u003cp\u003eThe magnification range in the basic configuration of the device is 40x to 1000x. You can add additional objectives to increase the upper limit of the magnification range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIllumination\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLEDs located at the bottom of the microscope provide bright and uniform illumination of the observed object. The color temperature remains unchanged when changing the brightness level. The illumination power is 3 W. It has a lifespan of 50,000 hours. The illumination system runs on an AC power source.\u003c\/p\u003e\u003cp\u003eBy adjusting the position of the Abbe condenser and opening or closing the aperture and field diaphragms, you can set up the Köhler illumination system. You can insert plates into a special slot in the condenser to use darkfield and phase contrast techniques. Thanks to these plates, switching from one observation technique to another is done very quickly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStage and focusing mechanism\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe stage has no positioning rack. Therefore, it will not be an obstruction during observations, and the microscope will take up less space on the workbench. The mechanical micrometer used to move the observed sample can be removed if manual scanning is desired.\u003c\/p\u003e\u003cp\u003eThere are coarse and fine focusing mechanisms for adjusting the focus. The adjustment knobs are located on both sides of the microscope. Because the knobs are located near the base, the user can rest their hands on the table instead of holding them in the air. This provides comfort during work sessions. The coarse focusing mechanism has a locking knob and a tension adjustment knob. Focus adjustment is smooth and effortless.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAccessories\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe capabilities of the MAGUS Bio 250TL microscope can be enhanced with the range of accessories, which includes eyepieces, objectives, calibration slides, digital cameras, darkfield, polarization, and phase contrast devices.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTrinocular head, 5-position revolving nosepiece, infinity-corrected plan achromatic optics\u003c\/li\u003e\n\u003cli\u003eEyepiece tubes can rotate 360° for a comfortable position that adjusts to the observer's height\u003c\/li\u003e\n\u003cli\u003eThere is a diopter adjustment ring on the left tube, coarse and fine focusing mechanisms\u003c\/li\u003e\n\u003cli\u003eThe coarse focusing mechanism has a locking knob and tension adjustment\u003c\/li\u003e\n\u003cli\u003eThe Abbe condenser is centered and height-adjustable, and the field and aperture diaphragms allow setting up the Köhler illumination system\u003c\/li\u003e\n\u003cli\u003eTransmitted light source: 3W LED with adjustable brightness and 220V power supply\u003c\/li\u003e\n\u003cli\u003ePossibility of installing additional accessories\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eThe kit includes:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBase with power connection, transmitted light source, focusing mechanism, stage, condenser holder and revolving nosepiece\u003c\/li\u003e\n\u003cli\u003eAbbe condenser\u003c\/li\u003e\n\u003cli\u003eTrinocular head\u003c\/li\u003e\n\u003cli\u003eInfinity-corrected plan achromatic objective: 4x\/0.10\u003c\/li\u003e\n\u003cli\u003eInfinity-corrected plan achromatic objective: 10x\/0.25\u003c\/li\u003e\n\u003cli\u003eInfinity-corrected plan achromatic objective: 40x\/0.65 (with retractable mechanism)\u003c\/li\u003e\n\u003cli\u003eInfinity-corrected plan achromatic objective: 100x\/1.25 oil (with retractable mechanism)\u003c\/li\u003e\n\u003cli\u003e10x\/22 mm eyepiece with eye relief (2 units)\u003c\/li\u003e\n\u003cli\u003eEyecup (2 units)\u003c\/li\u003e\n\u003cli\u003eFilter (4 units)\u003c\/li\u003e\n\u003cli\u003eC-mount camera adapter\u003c\/li\u003e\n\u003cli\u003eImmersion oil bottle\u003c\/li\u003e\n\u003cli\u003eAC power cable\u003c\/li\u003e\n\u003cli\u003eDust cover\u003c\/li\u003e\n\u003cli\u003eUser manual and warranty card\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAvailable upon request:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e10x\/22 mm eyepiece with scale\u003c\/li\u003e\n\u003cli\u003e12.5x\/14 mm eyepiece (2 units)\u003c\/li\u003e\n\u003cli\u003e15x\/15 mm eyepiece (2 units)\u003c\/li\u003e\n\u003cli\u003e20x\/12 mm eyepiece (2 units)\u003c\/li\u003e\n\u003cli\u003e25x\/9 mm eyepiece (2 units)\u003c\/li\u003e\n\u003cli\u003eInfinity-corrected plan achromatic objective: 20x\/0.40\u003c\/li\u003e\n\u003cli\u003eInfinity-corrected plan achromatic objective: 60x\/0.80 (with retractable mechanism)\u003c\/li\u003e\n\u003cli\u003ePhase contrast device\u003c\/li\u003e\n\u003cli\u003ePhase slider\u003c\/li\u003e\n\u003cli\u003eDarkfield condenser NA 0.9\u003c\/li\u003e\n\u003cli\u003eDarkfield oil condenser NA 1.36–1.25\u003c\/li\u003e\n\u003cli\u003eDarkfield slider\u003c\/li\u003e\n\u003cli\u003ePolarization devices\u003c\/li\u003e\n\u003cli\u003eDigital camera\u003c\/li\u003e\n\u003cli\u003eCalibration slides\u003c\/li\u003e\n\u003cli\u003eLCD monitor\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MAGUS","offers":[{"title":"Default Title","offer_id":52888767463767,"sku":"82891","price":1453.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/82891_magus-bio-250tl-microscope_00.jpg?v=1772207486","url":"https:\/\/astrotelescopios.com\/en-uk\/products\/microscopio-biologico-magus-bio-250tl","provider":"Astro Telescopios","version":"1.0","type":"link"}
